FLUID-COOLER.

SPEGIFICATIONforming part of Letters Patent No. 653,884, dated July 1'7, 1900. Application filed September 11, 1899. Serial No. 730,066- (No model.)

To all whom, it may concern:

Be it known that we, HENRY J. RICHARD and WALTER D. LENNOX, citizens of the United States, and residents of Danbury, in the county of Fairfield and State of Con necticut, have invented certain new and useful Improvements in Effervescent-Fluid Coolers, of which the following is a specification.

This invention relates to new and useful improvements in means for cooling, condensing, and cleansing effervescent fluids, and is especially adapted for bar purposes in drawing liquors, such as'beer, ale, porter, &c.

Our invention therefore has several important objects in view, the primary one being to provide a device which will quickly and thoroughly cool efiervescent fluids as they are drawn from the barrel; further, to produce a cooler in which the liquors do not have to remain over night, butmay be returned to the barrel, and, finally, in providing a receptacle and connections which are non-corrosive and may readily be disconnected and assembled for cleansing or repairs.

Heretofore a coil of pipe hasgenerally been employedfor cooling liquids of the above class; but said device is objected to by many for Several reasons, the principal one being that the liquids have to remain in it over night, thus becoming stagnant, and have to be thrown away in the morning; also, that the pipe corrodes and otherwise fills up from the sediment of the liquors and is very difficult to clean out properly.

With the above objects inview our invention resides and consists in the novel construction and combination of parts shown upon the accompanying drawings, forming a part of this specification, upon which similar characters of reference denote like or corresponding parts throughout the several figures, and of which-- Figure 1 shows a sectional perspective view. of our invention as it is situated when con-.

nected in practical operation. Fig. 2 is adetached plan of the cooler proper. Fig. 3 is a central vertical longitudinal section of the jar or cooler, taken on line 3 3 of Fig. 2. Fig.

4 shows a similar sectional view of a modified and simpler form of our invention. Fig. 5

shows a sectional plan View of a round or cylindrical" hollow jar, illustrating a further modification.

Referring to Fig. 1, which shows the general arrangements of the cooler and its con meeting parts, A indicates a floor, and B a counter, to which our improvements are fit ted. C represents an ice-box, which is shown as being formed integral with the counter; but it may be separate and detachable, if desired. Within this box is located one or more of our improved coolers, which we designate as D. Around said cooler and within the ice box is packed a quantity of cracked ice, which is replaced from time to time. A drain-pipe E is provided for said box and serves to take off the surplus water therefrom. F indicates a tank in which air or gas is stored, and G a pump which may be used to charge the tank. H represents a pipe leading from the tank, I a cock, and J a gage located in said pipe. A branch pipe K leads from the main pipe H and is provided with cocks L and M. A connection N is provided from pipe L to a distributing-pipe O, which latter contains'a series of spigots for delivering air to several barrels, if desired. P shows a connection from one of said spigots to a keg Q, whereby the compressed air is introduced and the liquors are forced up from the keg through the vertical pipe R, leading to the cooler. Within this pipe is situated a cock S, by means of which the liquor-supply can be cut off at any time.

Referring to Figs. 1, 2, and 3 for a more detailed description of the cooler proper, it will be seen that the same preferably comprises a hollow oval cylindrical body portion formed by an inner and outer shell a and b, which may be made of glass or porcelain-lined metal and which maybe termed a jar. The ends of these shells are closed by non-corrosive oval ring-like caps e and f, which are provided with suitable packings p to insure a positive inclosure and are provided with bolts g, which pass therethrough, extending across the inner and outer face of the cylinder, and are mounted with nuts h to clamp said parts together and form legs or supports for the same. These shells are held apart by a vertical wall 0 upon one side and stays (1 cl upon the other. The top cap is provided with three nipples or couplings 1 t, and t each of which forms a pipe connection, as will later be referred to. The pipe R, which leads from the keg, as before described, is attached to the coupling 1', from which a detachable extension j is provided to convey the liquor to the bottom of the cooler, where it is discharged and circulates around to the opposite side, from whence it is drawn for use through the pipes k k and spigot l. A third connection through nipple i is provided in the form of a short pipe m, which slightly projects through the top cap and which is provided with a cock n and has a nipple to which a flexible pipe may be temporarily connected.

From the foregoing it will be seen that the liquor enters the cylinder on the opposite side of the Wall 0 from which it is discharged and is thus insured a thorough circulation within the cooler and against the entire cooling-surface thereof. Owing to the pipesj and 70 extending near the bottom of the jar, it will be seen that the fluid when drawn off is taken solid, and consequently the excess foam which 4 is usually present from coil coolers is avoided.

By means of the couplings t, t, and t it will be obvious that the outer pipes may be readily disconnected from the cooler and the inner sections j and is likewise removed for cleaning and repairs, and, in fact, the cooler itself may also be opened for the same purpose by simply removing the bolts before mentioned, I

As before stated, the liquor is fed in the cooler under air or similar pressure through pipe R and is drawn from said cooler through spigot Z. If it is desired to cease the operation for a time-say for the night or the like it is simply necessary to close the spigot of pipe P and connect the flexible pipe 0 with the nipple of cock n, after which the latter is opened to admit the pressure of the tank into the cooler and whereby the liquors contained therein are all forced back into the barrel, after which the cock S is closed, leaving said cooler perfectly empty.

The modification shown in Fig. 4 illustrates a simplified form of jar which is particularly adapted for some kinds of liquors. In this view we have shown a plain jar having a cover q screwed thereon instead of a hollow cylinder, as illustrated in the other drawings. The piping in this device, as will be seen, is the same as that shown in the other figures, and consequently the method of operation is likewise similar.

We prefer to use an oval or oblong shaped jar, as shown in the first figure of the drawings, since it afiords a greater cooling-surface than a plain cylinder of equal capacity. We, however, do not wish to limit ourselves to an oval jar, as described, since for some purposes a hollow or circular ja'r, as shown in Fig. 5, is desirable, or a closed jar, as shown in Fig. 4, may be used.

Having thus described our invention, what we desire to secure by Letters Patent is- 1. In a cooling apparatus, the combination with a cooling-box, of a jar, inlet and outlet pipes with downwardly-deflected ends interior of said jar and both terminating adjacent to its bottom, means for returning the fluids from said cooling-jar back through the inletpipe into the barrel, as, and for the purpose specified.

2. In a device of the class described, the combination with cooling-box having an overfiow B, of a jar and support, supply-pipe R, a coupling and internal downward-extended detachable pipe j whereby the liquid is delivered against the bottom of said jar, outletpipe having spigot as shown, a coupling and internal-extended pipe for said outlet, and having its opening adjacent to the bottom, relief-pipe m provided with cock n, and means whereby the fluid can be returned from the jar to the keg, substantially as shown and described.

3. Ina cooling apparatus, the combination with a cooling-box, of a cooler adapted to be surrounded upon both the inner and outer sides with ice, a su pply-pipe leading through the cover to the bottom of said cooler, a relief-pipe entering the top of the cooler whereby the air or excess gases may be released, and means for returning the liquor from said cooler back into the barrel.

4. A liquor-cooling apparatus, comprising an ice-box, an oval jar located therein and havinga central opening therethrough, means for detachably closing said jar, an inlet-pipe to the jar having an interior downward-extended pipe disposed adjacent to the bottom, a cock to govern said inlet, an outlet-pipe from said jar leading up from the bottom and a spigot as shown, a relief-pipe and cook with a flexible .pipe for attachment, means for emptying said jar back through the source of supply to the keg, substantially as described.

5. The combination in a fluid-cooling apparatus, of a jar comprising an annular receptacle having an innerand outer exposed surface, rings with suitable packings to inclose said jar, bolts for clamping said rings in place,

inlet and outlet pipes through the cover and disposed near the bottom of said jar, means for returning the fluid from said jar back through the supply-pipe, substantially as shown and described.

6. A fluid-cooling apparatus, comprising a hollow, oval, cylindrical body, and caps inclosing said body, a vertical separating-wall 0 Within one side of said body, an outlet-pipe leading from the bottom of said body and situated at the opposite side of said wall from the inlet-pipe, and a connection for attachment with the pressure-cylinder for returning the fluid from the cooler through the inlet-pipe, substantially as described.
